Re: Clear ip OSPF process when cost is changed

Mohammed,

on Cisco routers you don't need clear ip ospf process to reflect the cost
for other routers.

You just need reload ospf process if you adjust the default OSPF reference
bandwidth.

Please, give us more information about your device, like vendor and version.

Rgs,
